The Opposite Side of the b ade opposed grooves ID in their inner Sides, said M may well carry a similar table 23 for use in shown in Fig 3 The side walls 1; are ,1 If a building thirty feet wide is to be proprovided with longitudinal slots ll unidirectional v d d wit r ft r hav a pitch f s x i h s with and substantially co-extensive in length to the foot, for example, the nut I6 is loosened with the grooves Ill, said slots ll opening into and the blade I4 is swung until one of the indie- 50 the central longitudinal portions of said grooves cating stubs 20 is directly at 6 on one of the 50 and opening also through the outer sides of the scales I3, as shown in Fig. 2, the nut It being walls I. Each slot H is of such transverse shape then tightened. By adjusting the tool in this that its side walls l2 diverge inwardly from each way, the body 6 and blade M are disposed at the other, and the portions of the two slots opening proper angle for cutting the upper ends of the through the outer sides of the walls 1, are very rafters and the cuts for the lower ends will, of 55 5 grooves being preferably of the longitudinal shape cutting p ra ters and Valley rafters. 45 v course, be at right angles to the upper ends, as usual. The length required for the rafters, may be determined from the table 22, showing said length to be sixteen feet, eight inches. The tool is similarly adjusted for cutting rafters of other pitches for buildings of diil'erent widths and in all instances, the required adjustment may be made quickly and easily, and the tool will save a great deal of time in marking the cuts.

As excellent results may be attained with the exact construction shown and described, it is preferably followed. However, attention is invited to the fact that variations may be made within the scope of the invention as claimed, and

it will be obvious that I am not restricted to any particular size or materials.

I claim:

1. A framing tool comprising an elongated body having two parallel longitudinal side plates, said side plates being provided in their inner sides with opposed longitudinal grooves, said side plates being also provided with narrow slots opening into the central longitudinal portions of said grooves and opening also through the outer sides of said side plates, a blade adjustably pivoted to one end of said body and foldable between said side plates, a link pivoted at one end to said blade and at its other end extending between said side plates, a straight pin passing transversely through the other end of said link and projecting in opposite directions from said link, said pin having its ends received in said slots to con stitute indicators, and rollers mounted on said pin at opposite sides of said link and received in said'grooves, said body having scales co-operable with said indicators for setting said blade.

2. A framing tool comprising an elongated body having two parallel longitudinal side plates, said side plates being provided in their inner sides with opposed longitudinal grooves, said side plates being also provided with narrow slots opening into the central longitudinal portions of said grooves and opening also through the outer sides of said side plates, the side walls of each of said slots being disposed in inwardly diverging relation, a blade adjustably pivoted to one end of said body and foldable between said side plates, a link pivoted at one end to said blade and at its other end extending between said side plates, a straight pin passing through; said other end of said link and projecting in opposite directions therefrom, said pin having conical ends disposed in said slots, said conical pin ends being in abutting relation with said inwardly diverging side walls of said slots, whereby said pin cannot slide endwise, the apices of said conical pin ends being visible at the outer sides of said side plates to form pointed indicators, and rollers mounted on said pin at opposite sides of said link and received in said grooves, said body having scales cooperable with said pointed indicators for setting said blade.

3. A framing tool comprising an elongated body having two parallel longitudinal side plates, the inner side of one of said plates being provided with a longitudinal groove, said one side plate being also provided with a narrow slot opening into the central longitudinal portion of said groove and opening also through the outer side of said one side plate, a blade adjustably pivoted to one end of said body and foldable between said side plates, a link pivoted at one end to said blade and at its other end extending between said side plates, a straight pin rigidly connected with said other endof said link and projecting laterally therefrom into said slot to constitute an indicator,

and a roller mounted on said pin and received in said groove, said body having a scale cooperating with said indicator for setting said blade.

4. A framing tool comprising an elongated body having two parallel longitudinal side plates, the inner side of one of said plates being provided with a longitudinal groove, said one plate being also provided with a narrow slot opening into the central longitudinal portion of said groove and opening also through the outer side of said one plate, the side walls of said slot being disposed in inwardly diverging relation, a blade adjustably pivoted to one end of said body and foldable between said side plates, a link pivoted at one end to said blade and at its outer end extending between said side plates, a straight pin rigidly secured to said other end of said link and projecting laterally therefrom, said pin having a conical outer end disposed in said slot, said conical pin end being disposed in abutting relation with said inwardly diverging side walls of said slot and having its apex visible at the outer side of said one side plate to constitute a pointed indicator, and a roller mounted on said pin and received in said groove, said body having a scale cooperable with said pointed indicator for setting said blade.
